The group 14 elements are the second group in the p-block of the periodic table. The atomic radii and melting point increase. Expert Answer: The word "chalcogen" is taken from Greek words being "copper-former," the meaning is more in line with "copper-ore former" or more generally, "ore-former." The prefix thio- in from of the name of an oxygen-containing compound means that the oxygen atom has been substituted with a sulfur atom. The most common oxidation state is -2; however, sulfur can also exist at a +4 and +6 state, and +2, +4, and +6 oxidation states are possible for Se, Te, and Po.

The name derives from the Greek Bi Methods to treat humans who have been contaminated with polonium are still being researched, and it has been shown that chelation agents could possibly be used to decontaminate humans. Oxygen is rarely the central atom in a structure and can never bond with more than 4 elements due to its small size and its inability to create an expanded valence shell. These can dissolve in water and react to form hydroxides; they are therefore called basic anhydrides or basic oxides.

Group 16 is the third last group in the periodic table.This group is called the oxygen family or the chalcogens.The elements in this group are oxygen, sulfur, selenium, tellurium, polonium and livermorium.The first two elements are nonmetals, elements are in between are metalloids and the last two are metals . It dissolves easily into dilute acids. Two common oxides of sulfur are sulfur dioxide (SO2) and sulfur trioxide (SO3). Typically, compounds with oxygen in this oxidation state are called oxides. ore forming elements since these elements are present in many metallic ores in the form of oxides and sulphides. However, because of its unstable nature it disappears and leaves the water unprotected from bacteria. Tellurium is the metalloid of the oxygen family, with a silvery white color and a metallic luster similar to that of tin at room temperature. To rank items as equivalent, overlap them.
